= Acknowledgements

First of all, I would like to express my gratitude to Vincent Nicomette and Julien Signoles, who agreed to be the _rapporteurs_ for this thesis, as well as to Olivier Barais and Simone Aonzo for being part of the Jury.

I'm also grateful for the support of my thesis advisors, Jean-François Lalande and Valérie Viet Triem Tong.
They trusted me to explore my strange ideas, reminded me to take things one at a time when I was overwhelmed by the number of issues one encounters when working with Android, and overall gave me great advice during those three years.
Now that I have finished my PhD, I can confirm that the curve of the evolution of the morale of the PhD student Jean-François drew me is pretty accurate.

I want to thank Marie Babel and Jacque Klein for being part of my _Commité de Suivi Individuel_, and my colleagues of the 5#super[th] floor, from both the PIRAT\\'); and the SUSHI team.
Those 3 years were fun, the croissants were good, and the conversations were weird.
What more could you ask for?
And I wish courage and good luck to those on the tail-end of their PhD, you're almost there!

As promised, I thank Amelie for proofreading my French summary.
I forgive you for the typos you missed.
Not as promised, I also thank you for the moral support and all the cute animal pictures exchanged during the last 3 years.

I also want to thank the _Pains-Perdus_, some of you may or may not have pushed me into doing a PhD, and you managed to endure my many rants about Android.

Last but not least, I thank my family.
Antoine for the good food every time I'm in the area.
Kpu for all the sword fighting when you were in Rennes, now that you have the HEMA virus, my job is done.
My mother, for giving me my first taste of infosec, even if it was definitely not on purpose.
Bypassing parental control on a wifi router is a great way to start.
And my father, for showing a 12-year-old me how to read and modify the source code of Battle for Wesnoth, who knew this first step in the world of reverse engineering would lead to a PhD?

Thank you.
